Well, stomata are the pores through which leaves breathe. These are also the pores through which transpiration takes place (Transpiration is the loss of excess water- just like in us, only we call it sweating). So if these pores were on the top of the leaf where sunlight falls directly, then there would be a lot of loss of water through evaporation and it is definitely not good to lose so much water.
So in order to reduce the chance of losing lot of water, these stomatal pores are in the lower leaf.

Because it will not lose that much water as compared to the top surface of the leaf.

Why are there more stomata on the bottoms of leaves?
This is because, to prevent water loss. If the stomata were on the upper side of the leaf, it would be in direct contact with the sun, which would absorb all the water from the leaf, when the stomata is open (which is around 9am and 3pm). This would not be essential for the leaf, as it would not be able to photosynthesise, hence, unable to respire, therefore, would die due to a lack of food and energy.
What will happen if there are too many stomata on the top of the leaf?
Stomata are a plants way of exchanging gasses in photosynthesis. The stomata also are resoponsible for transpiration. Most plants have stomata on the under side of the leaf in order to prevent too much water loss. There already is a lot of stomata in leaves but I think you mean to ask "What would happen if the stomata were open all the time?" this would result in mass water loss and cause a plant to wilt.Edited answer:Large number of stomata will increase porocity of the leaves and will facilitate better gaseous exchange and more transpiration.
Where does most transpiration occur in a leaf?
On the bottom of the leaves. This is because Stomata, the place in the leaf were gaseous exchanges of water and carbon dioxide occur, are more common in this part of the leaf compared to the top of the leaf. This is an adaption, because if plants had all of their stomata on the top of their leaves, excessive loss of water will be lost to the environment and cause dehydration of the plant and even potential death.
Which has more stomata the upper or lower epidermis?
Lower epidermis of leaves being away from direct sunlight have more stomata per unit area to minimize exessive traspiration.
How carbon dioxide enter the leaves?
stomata

Why Carbon-dioxide is absorbed more by lower leaf surface?
The underside of leaves is where the 'stomata' are to be found in most (not all) plants and it is through these stomata that the gas exchange occurs. The upper surfaces of leaves are usually tough and shiny to protect the leaf and shed water. If the stomata were on the upper surface and the leaf was wet, the water would block them and impede gas exchange.

Why do lotus and water lily have stomata on the upper surface of the leaf?
The stomata have to be able to access air easily as its purpose is to take in and give out carbon dioxide oxygen. Since both the water lily and lotus are water plants partially submerged in water, air would be more easily accesible from the upper surface.
What would happen what would happen if rita coated the leaves of her money plant with oil?
By coating the leaves of a money plant with will make these more shiny but it will harm the plant as oily coat will not facilitate exchange of air to and fro stomata.

How do gases enter and leave plants?
In terrestrial plants, gas enters and leaves (termed "gas exchange") through cell-lined pores called "stomata." Stomata open and close in response to light and humidity, permitting oxygen, carbon dioxide and water vapor to enter and leave the plant. In most terrestrial plants, the stomata are located on the surface of the leaves, or in cacti, on the surface of the stems. In aquatic plants, gas exchange directly though the tissue surface.
Where is the stomata located to reduce water loss?
Stomata are typically located on the underside of leaves. This positioning helps to reduce water loss by minimizing exposure to direct sunlight and reducing the chances of evaporation. The presence of stomata on the underside of leaves also reduces the risks of damage from external factors such as wind and heat.
How do curled leaves loss less water when compared to flattered leaves?
The percentage of humidity around stomata is more in curled leaves than those of flat leaves, hence the diffusion of water vapour is slower in curled leaves.
